screen fabric is removahly held in place by a retaining strip fitting in a corresponding member forming 'a part of, the frame proper. Screens of this sort are very commonly made of metal andone of the great hindrances to. the success of the same has been due to the enetration and accumulation of moisture inside of the frame. Moisture once penetratingthe interior of such frames does not have opportunity tobecome dried out, hence the continued rusting and rotting of the screen partsand everything with which it comes 1n contact. In the production of metal screens it is also desirable to have the frame light and yet strong both as a saving 6f the frame stock and also. to facilitate handling and to have the assemblage of the'parts and the replacement of the screening material accomplished with ease and facility. To the end of producing a screen which shallovercome these difficulties and offer these advantages and at thesame time afford a structure which Will-be simple, afford means 'for' the ready replacement of the screen fabric and afford other improvements and betterments I have devised my present invention which I will more fully set forth .in the specification which follows and which I have illustrated in the acehmpanying drawings forming a part of said specification by 40 an embodiment of .my invention which I have prepared as illustrative thereof.

in these drawings Figure 1 is a view of a corner portionof a screen, Fig. 2 is a side sectional view showmgthe retaming strip entered into the frame before rolling, Fig. 3

center thereof and arranged nearer the inner edge of the frame 1 so as to leave a broader space on the outer part of the frame.

3 is a wire retaining strip having flanges 4. The flanges 4- 0f the strip 3 are of such length. that when rolled down they will lie-inclined to the exposed portion of the stri and extending a greater distance from the line'of the strip than do the edges of the bead, sothat the horizontally disposed strips have .on their upper side. a flange whose upper edge is. elevated above the upper edge 3 of the exposed portion 3 of the strip. This affords a water shed and prevents the penetration of any water: which may run down against the exposed bead" 3*,0f the strip 3 and enter the slot 2.- Y I 6 is an angle piece having an inner beveled face 6 against which the flange 4 bears in its rolled position,-(see Fig. 3). The location of the slot 2 at one side of the frame piece 1 permits this angle piece 6 to be located in the corner and form with the frame ieces a strong joint, it being soldered into place.

The frame members are cut from stock strips of the desired shape with suitably initered corners and the corner anglcs ti are then secured therein by soldering or in any other suitable manner. The wire netting is then laid over the frame thus formed and its edges entered into the slots 2. Theastrips prepared in the form shown in Fig. 2,are then entered in the slots 2 and rolled down to 6X%LI1(l the flanges 4 into the position shown in ig. 3 in which position the exposed por tion of the strip 3 is left at the edges of the .slot 2 as a head 3 and the screen 5 is firmly clamped within the frame 1. The expan- -sion of the flanges 4 within the frame 1 eled ed' e 6 of the angle piece, affording additiona security in the Holding of the corner piece in the frame. obviously be of any length or extent and may be fastened in place in any suitable manner. Thus'constructed, the corner joints may be made from hollow stock which are strong and readily formed with little cost and the resulting frame is light and Well balanced. The flanges 4, being of greater height than the head 3 shed the penetrating water so that it readily dries out along the trough of screen frame internally and lengthening the life of the structure Various modifications may obviously he :brings them at the corners against the heva The corner angles may medial the head 3 thus insuring the dryness of the llO ' dinal recesses therein, strips in said recesses adaptedto hold therein the margins of a nettnr said strips comprising a body portion an -flanges adapted to enter said recesses, a

bead. along the body portion of each strip' and adapted to contact with the upper edge of its recess, theedge of the upper flange extending above the upperedge of said recess and above the upper edge of said bead.

2. In an article of the class described a horizontal frame member having a longitudinal recess therein, a strip in said recess adapted to hold therein the margin of a netting, said strip comprising a body portion adapted to lie outside of said member and flanges adapted to enter said recess, the edge of the upper flange extending above the upper edge of said recess and above the upper edge of said body portion.

3. In an article of the class described a pairof frame members suitably disposed to form a corner, said members having longitudinal recesses therein located near one'margm of each frame member, strips in said recesses adapted to hold therein the margin of a netting and a corner fastener disposed be tween said strip and the opposite sides of the said strips each comprising a body portion and flanges adapted to enter said recesses, a bead along the body portion of said strips and adapted to contact uith the edges of said recesses, the upper edges of the flanges of the horizontal strips extending above the upper edges of the said recesses and above the upper edges of said heads.

5. In an article of the class described hollow frame members united at their corners having longitudinal slots therein, strips in said slots adapted to hold therein the margin of a netting and corner blocks ha'vingbeveled faces adjacent to said strips and contacted thereby, said blocks being suitably secured within the two adjoining frame members of each corner.

In testimony whereof I aflix my signature in presence of two witnesses.
